Abstract

The non-toxic properties of plant distillate for application as corrosion inhibitors is an effective alternative to the toxic conventional derivatives currently applied in industries. Data on the corrosion inhibition effect of celery, pomegranate and green tea distillates on mild steel corrosion in 0.5 MH2SO4 from coupon analysis is presented. Results showed the distillates performed poorly at low concentrations from 15% to 45% distillate concentration. At 60% distillate concentration, their inhibition performance was average, but below the values for effective inhibition performance with final inhibition efficiency values of 54.55%, 48.65% and 32.39% for celery, pomegranate and green tea distillates. However, at 75% concentration, the inhibition efficiency values significantly increased to 85.74%, 82.85% and 62.70%. At 90% distillate concentration, the inhibition efficiency outputs of the distillates increased further to 95.83%, 87.08% and 92.37% signifying effective inhibition performance of the distillates. Statistical analysis through ANOVA shows distillate concentration strongly influence the corrosion inhibition performance of the distillates with values above 90% compared to exposure time with values below 7%, which is relatively negligible but statistically relevant. Generally, the results show the distillates are effective at high concentration with respect to distillate concentration.
